If you haven't seen the latest in Hummer tweaking, antics by the folks at Ihumpedyourhummer.com will shock and awe — as the case may be. The guys — who've spawned a weird little movement that's perfectly cast for Web video — prowl the streets on the lookout for humpable Hummers for their clips, which are set to music or remixed speechifying by Prez Bush or other dignitaries. It's our sincere hope that potential imitators, like those at igaveyourhummerahummer.com, won't burn their lips in an attempt at oneupsmanship.com.
